[Equipment] Resmed S9 Date Problem

[BrianDD]

I have an Resmed S9 Auto machine. Lately there is an issue where it loses the date and time if the machine loses power. Very frustrating as if I forget to correctly set the date/time time then the dates are wrong for when Oscar imports the data. In fact I can't find where it goes even the machine default is 1/2/2008!. I assume there is an internal battery which needs replacing - has any member been able to do this? Apologies if answer is somewhere on forum but I've searched and no luck. Thanks

It is a CR2232 (I think) and is located on the underside of the motherboard.

Here is the link to a S9's innards.: Inside View of ResMed pictures and the ResMed S9 Elite Teardown directions.

See the lower right for the battery location in the image below.
